How to move(translate) antenna using antenna toolbox

Hello,

I'm using antenna toolbox to extract E-fields (near/far-field).

But when I try to make an antenna, I don't know how to arrange the center of the antenna on the origin (since the antenna is automatically constructed using a simple function with frequency parameter)

I know how to tilt the antenna, but how to move according to any cartesian axis?

aut = design(horn, f0);

Anyone knows how to manyally move the antenna?

Thank you.

Hello Jaehoon,

You can try using the translate function which is available in the Antenna Tooolbox. I am attaching the example snippet of how we can translate a dipole antenna using translate function.

% Create a dipole antenna
dipole = dipole('Length', 0.5);

% Define the translation vector
translation = [1, 2, 3]; % [x, y, z] translation values

% Translate the antenna elements
dipole = translate(dipole, translation);

This function is available for most of the antenna elements in the Antenna Toolbox.

Hope this helps!!

Unfortunately, it does not work. I looked up doc of 'translate' and I also tried using two inputs for translation matrix (i.e. translation = [1,2];), but it still does not work. The error says 'The number of input and output values, or type is invalid.' (I translated it cuz it's shown in Korean. I'm sorry.)
